Figure 2 (as amended) is a perspective view of the same when open.

General Description.

I construct my improvement as follows: f The compression-cock Gis made of mv suitable metal, and substantially as shown in fig.` 2.

S-and'S are two perforations, made in the plate of which the compression-cock is made.

-Through these perforatious the tube F passes, ns shown, so that the stop-cock, whether closed or open,
